COMM Ports
To prepare the DSXpert unit for network communication, connect the COMM IN port on the
rear of the DSXpert chassis to a terminal or PC as shown in
for proper cable and pin connections.
The COMM (communication) ports provide a serial connection from the DSXpert unit to a
DTE (for example, a VT100 terminal or PC), DCE (for example, a modem), or other DSXpert
units. Primarily, the serial connection allows the DSXpert unit to be configured locally for
network communication. The network setup is continued in the Network Configuration
chapter.
For COMM port pin assignments, refer to . Different cable types are used depending on the
type of connection:
• Type 1 Cable: Connects COMM IN port on chassis to a terminal.
• Type 2 cable: Connects COMM IN port on chassis to a PC.
• Type 3 cable: Connects COMM IN port on chassis to a modem.
• Type 4 cable: Connects COMM OUT port on chassis to a COMM IN port on next
chassis.
• Type 5 cable: Connects COMM IN port on chassis to a CENTEST® 650 test device
(special application).
